Calcareous nannofossil and inoceramid biostratigraphies of a Middle Turonian to Middle Coniacian section from the Opole Trough of SW Poland
calcareous nannoplankton
biozonation
stratigraphy
Turonian
Coniacian
Well-preserved and rich nannofossil assemblages from Turonian-Coniacian (Upper Cretaceous) marlstone deposits of the Opole Trough in SW Poland have been analysed. Nannoplankton zones (and subzones) UC6 through UC10 were determined. Apparent discrepancies between the Turonian substage ages indicated by the nannofossil zones, which are based on correlations with the standard ammonite zones, and those based on inoceramids are revealed. This illustrates poor correlation between the inoceramid and ammonite events used to indicate the substage boundaries, rather than diachroneity in the nannofossil events.
